DETAILED DESCRIPTION OF THE INVENTION

The trigger group according to the invention is formed by an integrity of 18 different parts. The operation of trigger group is ensured by engaging and disengaging of the catches attached to the trigger group case (1) shown in 1 by the means of pins.

By the means of a cocking lever of the piston, the radius provided in front of the catch (2) and formed in accordance with the push and slide movement, pushes the surface and applies a rotating movement to the catch (1). During this rotation movement, the catch (1) is caught by the catch bearing formed on piston. The upper part of catch (1) caught by piston is caught by the catch holder (3) and thereby the catch (1) is not allowed to rotate which leads to prevention of piston from releasing.

While the cocking lever pushes the piston, it also pushes the safety sheet (11) provided on the trigger group, this in return brings the safety part (13) mounted on the safety sheet (11) under the stop on top of the trigger (5) and thereby accidental fall of trigger (5) by pressing on trigger (5) is prevented.

The safety tail (112) clinched on the safety sheet (11) is attached to the spring guide (10) by the means of a safety tail coupling bolt (9). Spring guide both guides to the execution spring, prevents bending of execution spring and also supports and acts as a bed of the safety tail (12).

With the cocking lever pushing the safety sheet (11), head part of safety tail (12) is elevated (since this part is made of plastic with an uneven surface, slip of a finger is prevented). Thereby the gun is secured. Trigger safety is formed so as to ensure that it will not be damaged in case it is attempted to re-cock the gun while the trigger is pressed.

Safety part (13) is attached to the safety sheet (11) by a safety part spring (16). If the gun is re-cocked while the trigger (5) is kept pressed, the safety part (13) leans on the side part of the stop provided on top of the trigger (5). When the trigger (5) is released, the safety part (13) gets free of the stop on the trigger (5). Thanks to the safety part spring (16), safety part (13) returns to its normal position. Thereby, neither the trigger nor the safety part is damaged.

The safety spring (15) attached on the trigger case fits into the channels provided on the safety sheet (11) and thus fixes the positions of safety sheet.

When the safety tail (12) is pressed down from its upward position, safety returns to its previous position and safety part (12) is released from the stop provided on the trigger (5).

Another safety system used is the manual safety system (FIG. 3). In this system, a safety sheet is replaced by a manual safety sheet (14). This part does not get effected by any gun cocking action. Cocking lever can not push the sheet because the manual safety sheet is short. Thereby the gun is not secured during cocking. It can be turned on and off manually, as the one wishes.

When the trigger (5) is pressed, trigger (5) leans on the catch releasing lever (4). Since the pin hole of catch releasing lever (4) is formed in a close vicinity of the trigger spring (7), the force applied to the lever is same at any distance. Catch releasing lever (4) presses (downwards) the trigger by the means of the trigger spring (7). As a result of the pressure applied to trigger, catch releasing lever (4) leans on the catch holder (3). Meanwhile a support gap is created. This support gap is formed so as to ensure that it can be adjusted via a trigger calibration bolt (18) provided on the trigger (5).

If the trigger calibration bolt (18) provided on the trigger (5) is fully tightened, the support gap is eliminated. Catch releasing lever (4) leans on the catch holder (3). It is possible to fall the trigger even when trigger calibration bolt (18) is unscrewed, thanks to the special form provided on trigger (5).

The trigger spring (6) located between the catch holder (3) and catch (2) makes these two catches a rotation movement in opposite directions. This spring is kept fixed by the means of a recess provided on the catches. When the catch releasing lever (4) presses the catch holder (3) by pressing on the trigger (5), it applies a force in order to release from the catch (2). There is a holding distance in which catch (2) and catch holding lever (3) hold each other.

Holding distance is provided so as to ensure that it can be adjusted via a catch calibration bolt (19) provided on the catch holder (2). Thereby, it is possible to adjust the load required until the trigger falls. The head of catch calibration bolt (19) has an uneven surface. Thereby, undesired slackening of catch calibration bolt (19) is prevented.

Such uneven surface of bolt head contacts with the inner wall of trigger case (1) and acts as a ratchet. In order to prevent an excess holding distance by unloosening the catch calibration bolt (19) too much, a case bush (17) is provided on top of the catch holder (2). Thereby, both excess elevation of catch holder (3) and in return falling of trigger device due to excess load is prevented and also the friction between catches and trigger case (1) upon undesired closure of case.

When trigger is pressed until the holding distance between catcher (2) and catcher holder (3) is fully covered, catch (2) rotates upon action of catch spring (6). This movement releases piston from catch. With release of piston from catch, the mechanism completes its task. With the air gun trigger group according to present invention that can be mounted separately on air sniper guns, time loss in manufacture is eliminated, production costs are decreased and also production process is easier because assembly with gun is ensured in most convenient way.
